gets a config db (cal_backend_file_destroy): release config db

2001-09-20  JP Rosevear  <jpr@ximian.com>

	* pcs/cal-backend-file.c (load_db): gets a config db
	(cal_backend_file_destroy): release config db
	(cal_backend_file_init): use load_db
	(mail_account_get): gets a mail account by number
	(mail_account_get_default): gets the default mail account
	(mail_account_is_valid): looks to see if any accounts have the
	given address
	(create_user_free_busy): modularize so we can call multiple times
	if necessary, set organizer
	(cal_backend_file_get_free_busy): if the list of users is null,
	use the default account otherwise get the same info for each
	address that is an identity in the mailer

	* gui/itip-utils.c (itip_addresses_get): s/gint/glong/ for bonobo
	conf returns

	* gui/calendar-commands.c (publish_freebusy_cmd): fix problems
	from a merge so that we publish 6 weeks of free/busy information
	again
